The star of "Napoleon Dynamite" is adding his star power to the already high-octane cast of a new Fox project. Deadline.com reports that Jon Heder will star opposite Jane Kaczmarek ("Malcolm in the Middle") and David James Elliott ("JAG") in the multicamera comedy pilot known as "Here’s Your Damn Family."

"The Warner Bros-produced multicamera comedy … centers on a stunted, intelligent but underachieving, set-in-his-ways thirtysomething man (Heder) living with his mom (Kaczmarek) who finds his perfectly organized world upended when she gets married — and her new husband (Elliott) plus his three teenage children move in," the story reports.
